Erratic SVG object transformation / rotation
Upon some testing it seems that it is not the rotation itself that is causing the distortion.

Eliminating the rotation transform from the first curve and importing again does make them overlap perfectly, but opening in Inkscape they both overlap perfectly regardless of rotation.

Scaling is the same for both objects, so that leaves only one culprit left: viewboxing

Your viewbox is causing distortions to your file as a whole, it becomes noticeable only in the transformed object.

If you manually edit your SVG file and remove the viewBox="0.000 0.000 1100 600" parameter, they both import fine and seem to overlap perfectly.
